Air freshener



FIG. 1 is a perspective view of an air freshener, showing my new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a side elevation view thereof, the opposite side being a mirror image of that shown; and

FIG. 4 is a bottom plan view.

In FIGS. 1 through 4, the openings, which are clear without shade marks within the openings, show an opening through the container while those openings showing shade lines are openings through the outer shell only and not into the interior of the air freshener. 

The ornamental design for an air freshener, as shown and described.
